Shared check-in kiosk at McCurran Airport in Vegas

I don't remember if I mentioned this here earlier, but I was looking at the etymology of co- words, e.g. community, collaboration, convict, confide, and so on. (Check out the Online Etymology Dictionary if you're into this.) I discovered that the word competition originally had nothing to do with fighting one another. It meant (Are you ready for this?) striving together. There's an idea for the airlines, eh?
